  • Publication number: 20210130531
    Abstract: In various embodiments, coated infill includes a plurality of infill granules and a preformed coating on the infill granules including a cured polyurethane product of at least one polyurethane prepolymer component and a curative component. The polyurethane prepolymer component includes a reaction product of an isocyanate component including diphenylmethane diisocyanate (MDI) and a polyol component, and has a free isocyanate content (% NCO) from 2 wt % to 12 wt %. The curative component includes water. Methods for making an artificial turf surface using the coated infill are also provided.

  • Patent number: 10662276
    Abstract: A cured composition including a reaction product of a mixture that includes an isocyanate component having one or more isocyanates and an isocyanate-reactive component having a butylene oxide based polyol, which has a number average molecular weight greater than 2,000 g/mol and less than 8,000 g/mol and a nominal hydroxyl functionality from (2) to (4). At least (50) wt % of a total weight of alkylene oxides used to form the butylene oxide based polyol is butylene oxide. An isocyanate index of the mixture is from (90) to (150). The cured composition in a cured state exhibits a first tan delta peak between a first temperature range of 50° C. to 0° C. and a second tan delta peak between a second temperature range of 75° C. and 150° C.

  • Patent number: 10626293
    Abstract: An acrylic polyurethane coating composition, comprising an isocyanate component comprising at least one polyisocyanate trimer; and an isocyanate reacting mixture, the isocyanate reacting mixture comprising from 25 wt % to 80 wt % of an acrylic polyol and from 1 wt % to 30 wt % of a polyether polyol, based on a total weight of the acrylic polyurethane coating composition, the acrylic polyol having a solids content of at least 50 wt %, based on a total weight of the acrylic polyol, and the polyether polyol having a viscosity of less than 500 mPa*s at 25° C. and a number average molecular weight greater than 300 and less than 700.

  • Patent number: 10487171
    Abstract: A curable composition includes a reaction product of an isocyanate component that includes one or more isocyanates, at an isocyanate index being from 90 to 150, and an isocyanate reactive component that includes a blend including from 5 wt % to 95 wt % of a first butylene oxide based polyol and from 5 wt % to 95 wt % of a second butylene oxide based polyol. The first butylene oxide based polyol has a number average molecular weight from 200 g/mol to 1,000 g/mol and a nominal hydroxyl functionality from 2 to 6. The second butylene oxide based polyol has a number average molecular weight greater than 1,000 g/mol and less than 8,000 g/mol and a nominal hydroxyl functionality from 2 to 4. The blend accounts for at least 50 wt % of a total weight of polyols in the isocyanate-reactive component.
